Authorizes municipalities and counties to lower speed limits on certain roads without engineering and traffic investigation.

This bill allows New Jersey municipalities and counties to lower speed limits by five miles per hour on specific roads without first conducting a mandatory engineering and traffic investigation. The authority to make these changes is limited to roads with existing limits of 35 mph or less located in school zones or designated high-pedestrian areas, which must include commercial downtowns, transit corridors, and zones near major transit facilities. To prevent overlapping studies and excessive reductions, the law prohibits lowering a limit more than once on the same road segment, setting a floor of 15 mph, and banning changes if a traffic study is currently underway or was completed within the last year. Local governments must establish clear criteria for identifying high-pedestrian areas and install appropriate signage to notify drivers of any new speed limits.
